Any GUI password dialog really ought to be taking the same precautions.

... gnome-keyring's SSH agent doesn't seem to be working right on my
system. I've been using "keychain" but it should be disabled at the
moment.

Does it really implement its own ssh agent? That would be really
annoying as that would break interoperability with non-GUI logins. I ssh
in and use screen on this box as well. "keychain" was handling all cases
seamlessly, with this small fix:

ln -s /etc/profile.d/keychain.sh /etc/X11/xinit/xinitrc.d/keychain.sh
